+### Autocomplete
+
+If you're still looking to save some typing time, Pulsar also ships with simple
+autocompletion functionality.
+
+The autocomplete system lets you view and insert possible completions in the
+editor using <kbd>Tab</kbd> or <kbd>Enter</kbd>.
+
+![Autocomplete menu](@images/atom/autocomplete.png "Autocomplete menu")
+
+By default, the autocomplete system will look through the current open file for
+strings that match what you're starting to type.
+
+If you want more options, in the Settings panel for the autocomplete-plus
+package you can toggle a setting to make autocomplete-plus look for text in all
+your open buffers rather than just the current file.
+
+The Autocomplete functionality is implemented in the
+[autocomplete-plus](https://github.com/pulsar-edit/autocomplete-plus) package.
